binder Circular Connector, 4 Contacts, Cable, Subminiature Connector, Plug, Male, IP40, 719 Series

Binder 719 Series Circular Connector, 4 Contacts Pole Format, 3A Current - 09-9767-70-04

This circular connector is a Compact electrical plug designed for cable mounting in industrial and automation settings. It provides a straightforward straight, male connection with four conductors and is suitable for installations requiring a low-profile, subminiature interface. The housing is MADE from a Durable engineering polymer and the device mates via a snap-in arrangement for quick assembly in confined spaces.

Features and Benefits:

• Four-contact arrangement enabling multi-signal or power distribution
  Gold-plated brass contacts ensuring enhanced conductivity and corrosion resistance
  Solder termination for secure, permanent conductor attachment
  Rated for 3A continuous current to support modest loads
  Operates up to 70°C for higher temperature environments
  IP40 protection level suitable for indoor, non-watertight enclosures

Applications

• Suitable for sensor and actuator cabling in automation cabinets
  Ideal for interconnections in control panels and small machinery
  Used with Compact motor controllers requiring multi-pin inputs
  Can be used for signal routing in laboratory test rigs

What type of mating action does it use and why is that useful?

It employs a snap-in mating method, allowing fast, tool-free engagement and reliable retention in assemblies where frequent connection cycles are not required.

What are the material choices for the contact and housing and their advantages?

Contacts are brass with a gold finish to reduce contact resistance and improve longevity, while the housing is polyamide to provide mechanical strength with low weight.

How does the connector perform electrically in low-voltage systems?

It is specified for operation up to 60V and can carry 3A, making it suitable for many low-voltage signal and light-power applications.

What environmental limitations should be considered during installation?

The connector is rated IP40, so it should be used in clean, indoor environments free from significant dust ingress or liquid exposure.
